B&B Spoilers: Finn makes an unforgivable mistake, Steffy asks for a 𝖽𝗂𝗏𝗈𝗋𝖼𝖾

The Bold and the Beautiful (B&B) spoilers reveal that Steffy Forrester (Jacqueline MacInnes Wood) will snap as John “Finn” Finnegan (Tanner Novlan) breaks a promise, so here’s how Luna Nozawa (Lisa Yamada) will torpedo their marriage.

During the week of March 31-April 4, Finn will have Luna on his mind.

In fact, it’s safe to say Luna has rarely left Finn’s thoughts since he got updates on her true paternity.

It was one thing for Finn to turn his back on Luna when she was just his wayward adoptive cousin.

It’s quite another for Finn to intentionally abandon Luna knowing she’s his biological daughter.

Of course, the news of Luna’s pardon left Steffy reeling, so she turned to Finn for confirmation that he understood the danger here.

Steffy is counting on Finn to keep the protective promise he’s made when it comes to defending their family.

Finn has repeatedly assured Steffy that he’s committed to keeping her safe along with the kids.

However, the truth is that Luna is Finn’s kid, too – and that’s changed things in his heart.

That’s why Finn will have a hard time going along with the agreement he made with Steffy regarding Luna.

Although Finn has tried shutting Luna out, it’s obviously not going well if he’s already wavering on his vow to Steffy.

In B&B’s preview video for the week of March 31-April 4, Steffy snaps at Finn and offers a stern reminder Luna can’t be anywhere near them or the children.

Based on Finn’s expression, he’s clearly not sold on the idea of eliminating Luna from his life forever.

Finn might hope for some compromise where he can have a relationship with Luna as long as he keeps her away from Steffy, Kelly Spencer (Sophia Paras) and Hayes Forrester Finnegan (Alexander and Chase Banks).

Unfortunately, that’s not going to work for Steffy if she picks up on Finn’s changing perspective.

Steffy will stand her ground on a total Luna ban, so major drama’s looming.

The more Finn starts opening his heart to Luna, the more things are going to fall apart with Steffy.

Finn’s point of view will continue to shift – and that could bring a disastrous outcome for his marriage eventually.

The Bold and the Beautiful spoilers say Sheila Sharpe (Kimberlin Brown) will make additional family predictions and try to help Luna get everything she wants – including a real father-daughter bond with Finn!
